One objective is to develop reliable ways and means other than parachutes/parawings to decelerate, descend and revover payloads lost during pre-orbit launch failures, improper orbit insertion and spacecraft operational failure in space, suborbital and near-space applications. Another objective is to eliminate uncontrolled payload free-fall trajectory into restricted or populated areas, and use pro ...

An innovative distributed multi-axis fiber optic based strain sensor system will be used to measure transverse strain, longitudinal strain, and strain gradients in adhesive bonds to track the onset of failure. This system which is based on advanced fiber grating technology allows multiplexing of large numbers of sensors, Synergy with the communications industry allows the unit cost of the sensors ...

The goal of this project is to develop ConsensusBuilder, a collaborative working environment which supports distributed team argumentation, negotiation, and consensus building through decision support. Based on a natural model of team decision making, this system enables the capture of the design rationale in value-added activities. Team support is provided for ad-hoc activities, those based on ...

Techical advances in two dimensional staring focal plan arrays (FPSs) have stimulated research to utilize FPSs in spectrometer instrumentation with the goal of increased spectral, spatial and temporal resolution. Conventional staring FPA spectrometers create a three dimensional image (two spatial and one spectral) by either using a sequence of narrow band spectral filters to slice the ...

Malaria infects over 200 million people and is responsible for 2 million deaths annually. Flow Inc. has developed diagnostic procedures based upon the fact that the parasite contains an enzyme lactate dehydrogenase (pLDH) (US patent 5,124,141). Recently, Flow Inc. has increased the sensitivity of its diagnostic procedures to detect 50 parasites/ul with the use of monoclonal antibodies (US Patent ...

This program would build upon recently completed work sponsored by DARPA and carried out by the team of Pratt & Whitney (P&W), Lucent Technologies (AT&T prior to 1/1/96), with Hood Technologies and Summit Applied Research as small business subcontractors. That work demonstrated the feasibility of using active control techniques to reduce resonant forced vibration levels in gas turbine rotor bl ...

We propose to upgrade a blade vibration monitoring system developed 15 years ago: 1) to improve its sensitivity and vibration measurement capability with the goal of using the improved system in on-going research in active high-cycle fatigue abatement for rotor blades; 2) develop the system, especially its electronics and software, and bring it to current aerospace industry standards to become the ...

This project addresses the problem of exciting rotor blades of a rotor spinning in an evacuated spin pit. The excitation is periodic at a harmonic of the spin frequency.The proposal surveys preceding excitation methods and explains why each is unacceptable. The proposed method circumvents the shortcomings of these prior techniques.

We propose starting a commercial Internet website that will provide access to a variety of computer codes for the purpose of analyzing rocket engines and rocket engine components. Users will be able to execute well-maintained computer codes over the Internet. The codes found on the website will be an improvement on what is currently available since they will be maintained and upgraded by a conso ...

This proposal addresses a design and fabrication investigation of a volume photorefractive optical memory system. The technology supports integration into two dimensional (2D) arrays of reconfigurable optical interconnect pixels for high performance digital processing applications such as high speed telecommunications and computing. The proposed volume memory array will be integrated into the hi ...
